A case of tuberculosis verrucosa cutis in Brazil undiagnosed for 15 years

ABSTRACT Tuberculosis verrucosa cutis is a rare medical condition that is caused by the inoculation of Mycobacterium tuberculosis into the skin of a previously sensitized individual. This clinical form of tuberculosis corresponds to 1-2% of all cases of tuberculosis and due to the paucibacillary characteristic of the lesions, patients can be misdiagnosed, accounting for the chronification of the skin infection. Herein, we report the case of a 26-year-old male farmer, presenting plaques with verrucosa and hyperkeratosis features in the left thigh and buttocks during 15 years. M. tuberculosis was identified by PCR and the patient was treated with standard anti-tuberculosis drugs, with subsequent improvement of the skin lesions.

Multinucleate cell angiohistiocytoma: an uncommon cutaneous tumor

Abstract Multinucleate cell angiohistiocytoma is a rare, benign vascular proliferation of unknown etiology. It occurs mainly in middle-aged women and usually affects the acral regions; the lesions appear as discrete, grouped, and asymptomatic violaceous papules. Histopathology shows proliferation and dilated small vessels in the papillary dermis, fibrous stroma with thickened collagen bundles, and multinucleated giant cells. To date, there are approximately 140 cases described in the indexed literature. This report presents the case of a 62-year-old woman with a typical clinical condition, who chose not undergo treatment, considering the benign character of her illness. The clinical and immunohistological aspects of this unusual dermatological entity are emphasized.

Translation into Portuguese language (Brazil), transcultural adaptation and validation of the quality of life questionnaire in female pattern hair loss (WAA-QoL-BP)

Abstract: Background: Female pattern hair loss (FPHL) is a common complaint in adult women and inflicts major impact in quality of life, however, there is no specific questionnaire available in Portuguese for such evaluation. Objectives: Translation into Brazilian Portuguese, cultural adaptation and validation of the WAA-QoL (Women's Androgenetic Alopecia Quality of Life Questionnaire). Methods: Methodological study. After authorization by the author, cultural (linguistic) translation and adaptation to Portuguese of the WAA-QoL questionnaire were carried out. The translated version (WAA-QoL-BP) and DLQI (Dermatology Life Quality index) were submitted to patients with FPHL for concurrent validation. Twenty patients were reevaluated to assess temporal stability. Results: A total of 116 patients with APF were evaluated, the mean age (SD) was 47 (14) years, and 89 (76%) patients were classified as grades II and III (Sinclair). There was high internal consistency: Cronbach´s alpha was 0.97 for the WAA-QoL-BP and 0.87 for the DLQI. The correlation between WAA-QoL and DLQI resulted in (rho) 0.81 (p <0.01). The intraclass correlation coefficient for complete agreement of WAA-QoL-BP was 0.95 (p <0.01) in the test-retest comparison. Study Limitations: Sampling of patients only from the State of São Paulo. Conclusions: A Brazilian version for WAA-QoL was translated and adapted, which proved to be valid and consistent.

Sarcoma de Kaposi em paciente portador de HIV: relato de caso / Kaposi sarcoma in a patient with HIV: case report

Sarcoma de Kaposi é um tumor maligno originado do endotélio vascular que acomete principalmente pele e mucosas. Geralmente, é associado à síndrome da imunodeficiência adquirida ­ aids, apresentando lesões vinhosas, arredondadas que, com o passar dos dias, tornam-se purpúricas, elevadas e com distribuição multifocal. Nesse estudo é relatado o caso de um paciente do sexo masculino, de 42 anos de idade, de fototipo IV, com emagrecimento, diarreia, pápulas e placas eritemato-violáceas nos membros inferiores. Durante a internação, encontrou-se sorologia positiva para HIV e ao realizar histopatológico das lesões cutâneas, confirmou-se o diagnóstico de sarcoma de Kaposi. O objetivo do presente estudo é ressaltar que quando presente infecção pelo citomegalovírus em paciente com aids há maior predisposição para o desenvolvimento de tal neoplasia. (AU)

Kaposi's sarcoma is a malignant tumor originating from the vascular endothelium, which mainly affects the skin and mucous membranes. Generally, it is associated with acquired immunodeficiency syndrome - AIDS, presenting rounded, wine-like lesions that become purpuric, elevated, and multifocal in the course of days. In this study the case of a 42-year-old male phototype IV with weight loss, diarrhea, papules and erythematous-purple plaques in the lower limbs was reported. During the hospitalization, positive serology for HIV was found and the diagnosis of Kaposi's sarcoma was confirmed in the histopathological examination of cutaneous lesions. The objective of the present study is to highlight that when present with cytomegalovirus in a patient with AIDS there is a greater predisposition for the development of such neoplasia. (AU)

Congenital plaque-like glomangioma: report of two cases

Abstract: Glomus tumors are rare hamartomas that originate from the glomus body. These tumors can be divided into solitary and multiple, the latter also known as glomangioma. We report the case of two patients with a rare variety of glomangioma called congenital plaque-like glomangioma. It presents as numerous red to bluish compressible papules, that increase in size in proportion with the weight and height growth of the child. Diagnostic confirmation is with histopathology and the treatment is surgical.
